Ally Solowicz Professor Sanstad Biology 101 29 July 2016 Lab 13 The way to form a hypothesis is to first form observations, and see what all of the observations have in common, so for the hypothesis in this lab, it would be that because all of the observations suggest that predators may influence guppy color patterning, promoting crypsis when predation pressure is high, and conspicuousness when it is low, then the hypothesis would be that if predation on a guppy population is high, a less conspicuous color pattern will be more prevalent in the population. If predation is low, a more conspicuous color pattern will be prevalent in the population. The first steps of the lab are to set up the experiment. You first have to set up two separate experiments, a greenhouse experiment and a field experiment, and create ten artificial ponds with sizes and contours designed to mimic the natural environments of the guppies. Then add predators into the pools with the guppy population. Then, through fourteen months, you

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
